SAD-IRON HEATER.

SPECIFICATION forming part of Letters Patent N0. 227,081, dated April27, 1880.

Application filed September 520, 1879.

To all whom it may concern:

Be it known that I, HARVEY L. WELLS, of Evansville, in the county ofVanderburg and State of Indiana, have invented a new and ImprovedSad-Iron Heater, of which the following is a specification.

Figure 1 is a front elevation of the device, partly in section. Fig. 2is a plan of the same with part broken away. Fig.3 is a transversesectional elevation on linem a, Fig. 1. Fig. 4 is a sectional elevation,showing the valve and certain other parts enlarged.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a simple, safe, and efficientdevice in which light oils may be used as fuel for heating sad-irons fordomestic use, or for the use of tailors, dress-makers, &c.

The invention consists, essentially, of an iron box dividedlongitudinally into two chambers, the lower being the combustion-chamberand the upper the heating-chamber.

The heating-chamber is divided by vertical partitions into severalreceptacles for the sadirons, each one of which is open in front for theeasy entrance and withdrawal of the irons, and has an opening in thetop, through which the handle of the iron may protrude to keep cool.Between these receptacles are narrow openings or chimneys for the upwardpassage of heat and gases. This upper chamber may be detached at anytime and the rest of the apparatus be applied to the purposes ofcocking, the cooking utensils being set on top of it. These chambersrest on suitable upright supports, from which rise at the ends of thedevice the supports of the oil-reservoirs, that set higher than thechambers and at a safe distance from them. From these reservoirsdescends a main pipe, from which branch at right angles several othertubes to supply oil to the burners in the combustion -chamber. The flowof oil to the burners is regulated by valves, and the burners have novelauxiliary devices, all which will be herein after more fully described.

In the drawings, A represents the combustion-chamber B, theheating-chamber, divided into the receptacles O by the partitions a.

These receptacles O are open in front, and have openings b in their topsfor the projection of the handles of the irons. D are the flues orchimneys between and at the sides of the receptacles G,connect1ng withthe combustionchamber A. In the closed front of the combustion-chamberAare the openings 0 through which air may be admitted to aid in the combustion of the generated gases, and which also serve asinspection-holes, through which the flame of the burners may be observedto be regulated, if desirable.

E are the standards supporting the device. F are the supports of theoil-reservoirs G. H are the pipes leading down from the reservoirs G,through which pipes H the oil flows into the tubes I, that extend intothe combustionchamber A. Within these tubes I are designed to be theconical valve-seats d, with small orifices for the oil to flow through,and through the free ends of the tubes are entered the pointed valves K.that regulate the flow of oil. Projecting upward from these tubes 1 arethe burners L, provided with small bores reaching downward into thetubes I.

M is a perforated cap set over the burner L to spread the flame, andthis cap M is sup ported by a rod, j", that conducts heat to the tube I,to convert the oil therein, or a portion of it, into vapor.

N is a cup suspended by a tube, g, below the burner L, on the oppositeside of the tube I. IVhen the device is to be put in operation a littleoil is permitted to flow into the cup N, where it is set on fire, thatit may heat the tube I and generate gas therein that shall escape at theorifice of the burner L, where it will be lighted for the purpose ofheating the sad-irons, and as the work continues the heat reflected uponthe tube I by the cap M, and conducted by the rod f, is found to besufficient to vaporize the oil passing through the valve-seat d andconvert it (the oil) into a gas, that escapes and is burned at theburner L, thus supplying all the heat that is desired.

On the bottom of the sad-iron receptacles are circular plates 0, whoseobject is to deflect the flame and thus create an upward draft, so thatsufticient air may be drawn in through the opening 0 to cause thecomplete combustion of the gases and the consequent absence of soot.

P are the handles by which the device may be moved.

These heaters may be made of any size to heat one or more irons, and ofsuch shape that when the upper chamber, B, is removed the top of thecombustion-chamber A will accommodate the cooking utensils ordinarilyused. These heaters are constructed to be fastened on a platform orboard, or on the ironing-table, and are found to be well adapted to thework for which they are designed.

I am aware that burners and valves some what resembling mine have beenused before; hence I do not broadly claim them; but,
